How to Care for Gymnocalycium Mihanovichii ‘Sphinx’ Clone
The ‘Sphinx’ Clone is relatively easy to care for, thriving with proper light, well-draining soil, and a mindful watering routine.
Light Requirements
- Prefers bright, indirect sunlight or filtered morning sun for optimal growth.
- Avoid intense afternoon sun, which can cause scorching on its lighter yellow areas.
- Indoors, position near a south- or east-facing window to maintain its vibrant colors.
Soil and Potting Mix
- Requires a well-draining cactus mix with extra perlite or pumice to prevent root rot.
- A shallow terracotta or ceramic pot is ideal for better moisture control and aeration.
Watering Routine
- Follow the “soak and dry” method:
- Water only when the soil is completely dry to prevent overwatering.
- Reduce watering in fall and winter, as the plant enters dormancy.
Temperature and Humidity
- Thrives in 65-85°F (18-29°C).
- Not frost-tolerant – If temperatures drop below 50°F (10°C), move it indoors.
Fertilization
- Use a low-nitrogen cactus fertilizer once a month during the growing season (spring and summer) to support healthy growth and maintain its vibrant coloration.
- Do not fertilize in winter, as the plant’s metabolism slows down.
Propagation
- The ‘Sphinx’ Clone may occasionally produce offsets (pups), which can be gently removed and replanted.
- Grafting onto a Hylocereus rootstock can help boost its growth rate and preserve its form.
